-*M -IMPROVED CHAIR-FRAME.

The Scheule referred to in these Letters Patent and making of the same.

To all whom: it Imay concern Be it known that I, WILLIAM M. SMITH, of Columbus, in the countyof Franklin, and State of Ohio, have invented a new and useful invention, being an Improved Chair-Frame; and l do hereby declare that the following is a full and exact description thereof, reference being had to the annexed drawings, as forming a part of this specification.

Nature and Ubjects of the Invention.

the position to be occupied by the seat-frame is reached, v

the material develops anoutward curve, and is thenbent downward and' backward, to lan angle of about forty-tive degrees to the perpendicular of the part,` the extremity whereof meets the supporting-surface. A

When the piece is bent as last aforesaid, it is con- -tiriu'ed to one of the posts of the backA ofthe chair,

towhich it is secured, and is then again bent laterally, at an angle of forty-tive degrees or more to that part of the piece beside the seat-frame, and passes in front of theother post ofthe back of the chair, forming an arch between the two posts. The piece is again curved laterally, and the other side of the frame is completed, and also the other,l front leg. is provided' with braces or rounds, pins, and other usual means required to retain it in the desired shape.' It will be thus seen that this piece forms the frontlegs or supports, and the frame to enclose and sustain the chair-seat. v

The Apart enclosing the seat-frame 'on three sides may itself be used as a seat-frame, by having abar passing from one side tothe other, connectingr the opposite sides of the frame, at the same height from the ends of the supports or legs as the hack part of the frame is above the surface upon which the chair stands, and at a proper distance from the front of the frame, and then iilling the space enclosed between the lateral curve of the Iiame and the bar, with -a seat of cane, wood, or other material.

rIl he piece forming the back and rear legs of the chair-frame has a slight curve, from its extremities or feet, inward, until it reaches the part ofthe piece aforesaid which encloses the rear ofthe seat-frame. 1t thence curves l,in a reverse direction. At the de sii'ed height, the piece is curved laterally and downward, so as te formthe archof the back of the chair- This piece of materialframe, which arch is formed with a slight lateral concavity. This' piece. is provided with the proper rounds, pins, and other means to secure it to the piece irst above mentioned, and in the proper shape.

The seat-fra me is composed of one piece of material, bent into the desired form. The ends are lapped and secured together by usual means. lhis frame is filled with woven cane, cloth, or other desired material, and is supported by that portion of the piece first above mentioned, which encloses it on three sides, and to which it is' fastened by ordinary attachments.y

My invention can be used either with or without rounds or stretchers, when the material is properly prepared.

Description of the Accompanying Drawings. Figure l isa perspective view of the invention. Figure 2 'is that part of the frame forming the front legs and enclosing the seat-frame.

Figure 3 is that part of the frame forming the rear legs and back of the chair-frame.

Figure 4 is the seat and seat-frame..

Figure 5 is a section of'tig. 4, through the line a.' a".

General Description.

I take a strip or bar of wood, (ash, oak, and hickory y i and then 'conformed to the desired shape.' If metalbe used, it should be ductile or malleable.

. The pieces, figs. 2, 3, and 4, are thus described:

Fig. 2 is composed of one piece of material. Above the endv or foot c, there isa slight inward curve to the point b,- where a round, d, serves to secure the front leg to the rear leg of theflame. From the point b, the'. piece curves graduallyl outward .to the point e, where it again curves downward and backward to the point f,- where it is attached to the piece, tig. 3, by a. pin or other known means, at g g. The piece is secured to thc seat-frame, tig. 4, by pins or ordinary attachments. From the point f, the piece is bent iut-o au arch, the end opposite thepoint f passing in front of the post ofthe chair-back, tig. 3, to the point 7.-, and is there attached to said post by ordinary means.. It then is bent similarly to the opposite side.

The rounds ll c ll c' serve to attach the legs or supports of fig. 2 to the corresponding parts of iig. 3.

Thev round s attaches the legs or supports of g. 2 to each other. l

The front of fig. 2 is slightly elevated above the rear, as shown by the dotted lines w y.

Fig. 3 is composed of one piece of material, which is formed into the desired shape, by the means afore said, and has a gradual curve forward from the foot' or extremity to the pointrm, where it is attached to that portion of iig. 2 enclosing the rear of the seatframe, fig. 4. Thence it curves backward, unt-il it reaches the point n, where it is bent into the arch of the upper part of the chair-back, which arch has a slight concavity in front, as shown by the dotted lines a' u". The opposite side is similarly formed to` that described.

Rounds, at o o', serve to connect the opposite legs of iig. 3, which are attached to the supports of lig. 2 by the rounds c cl c d. y

The slat sl connects the opposite parts of iig. 3, which, in conjunction with the slat s, form the' back of the chair-frame.

Fig. 4 is composed of one piece of material, bent, by ordinary processes, into the desired shape, and is iilled with a seat of any proper material. This frame is secured to the interior of thc laterallycurved portion of ig.2, by pins or other attachments, at g g. The ends of this frame overlap each other aty the points :c af, and are fastened together by suitable means.

rlhe periphery of this frame should conform to the. interior of the laterally-curved portion of iig. 2. The frame is so placed that the rear portion s somewhat lower than the front.

'lhe chair-frame is thus formed from the foregoing parts:

First take the part, iig. 2, and expand the supports thereof suiiciently to adjust the round z. Place the rounds c d c el in the apertures provided. The rounds o and o and ,the slat s are then similarly adjusted in the part, fig. 3. The parts, fig. 2 and fig. 3, are then joined in the usual manner, and are fastened to each other, by pins or /other suitable means, at the points f and f. The seat-frame, lig. 4, provided with a seat, is then placed in the space between the horizontal part of the part, fig. 2, so that its upper edge is on the same level with the adjacent part of lig. 2, and is there prope erly secured.

' Claims.

I claim, as my invention- 1. The part, fig. 2, as shown and described, when constructed and used in the manner and for the purpose specified.

2. T he combination of the parts as shown in gs. 2, 3, and 4, constructed and used in the manner speci- WM. M. SMITH.
